Description

[Detailed Description of the Invention] This invention relates to a side defroster for an automobile that allows connection of air pipes at low cost.

In automobiles, warm air is blown onto the front and side windows to prevent them from fogging up during rainy weather, but the side windows are attached to the doors, which can be rotated on hinges. Connecting the defroster to the air pipe is troublesome.

Therefore, a trumpet-shaped elastic piece that communicates with the tip of the air flow pipe is attached to the instrument panel, and this elastic piece is connected to the inlet of a side defroster provided in the door.

That is, FIG. 3 is a partially cutaway plan view showing the connection between the conventional side defroster and the air pipe, and shows a trumpet-shaped elastic piece C inserted into a hole provided on the side surface of the instrument panel a.
At the same time, the end of the bellows-shaped blower tube d is attached to the inner surface of the instrument panel a via a hose joint e, and the blower tube d is connected to the elastic piece C in a continuous manner.

When the door f is closed, the outer peripheral edge of the elastic piece C comes into contact with the outer periphery of the entrance of the side defroster g provided on the door f, and the hot air sent through the air pipe d is transferred to the elastic piece. C and is supplied into the side defroster g through the inlet.

Therefore, in such a device, a trumpet-shaped elastic piece C is attached to the instrument panel a, and the air pipe d is connected to the elastic piece C by a hose joint e.
It is necessary to install the device in communication with the device, which results in problems such as a complicated structure and high manufacturing cost.

In view of this point, this invention has been improved so that it can be made at low cost, and an embodiment of the invention shown in the drawings will be described below.

A hole 2 is provided in the side surface of an instrument panel 1 in front of a driver's seat of an automobile on which instruments and the like are mounted.

Then, the tip of the bellows-shaped blower tube 3 whose base end is connected to the heater is made to protrude from the hole 2.

The bellows-shaped air pipe 3 is fixed to the instrument panel 1 inside the hole 2 with a fastener 4.

On the other hand, a side defroster 6 is provided on the door 5 on the side of the driver's seat, and the lower entrance of the side defroster 6 is opposed to the tip of the bellows-shaped air pipe 3.

8 is a side glass. The effect will be explained.

The bellows-shaped air pipe 3 is fixed by a stopper 4, and the portion protruding from the hole 2 of the instrument panel 1 has elasticity in a free state.

When the door 5 is closed, the tip of the bellows-shaped air pipe 3 comes into close contact with the inlet 1 of the side defroster 6.

As a result, the bellows-shaped blower pipe 3 and the inlet 1 of the side defroster 6 are directly connected, and warm air is blown from the side defroster 6 and blown onto the side glass 8 to remove fogging.

When the door 5 is opened, the bellows-shaped blower pipe 3 freely extends.

The side defroster 60 inlet 1 is separated from the bellows-shaped air pipe 3, and there is no problem in fully opening the door 5.

As explained above, this idea involves protruding the tip of a bellows-shaped air pipe into a hole provided on the side of the instrument panel, and fixing the bellows-like air pipe inside the hole in the instrument panel with a stopper. However, since the tip of the bellows-shaped air pipe is made to come into elastic contact with the inlet of the side defroster installed in the door, the tip of the bellows-shaped air pipe can be directly connected to the inlet of the side defroster, unlike conventional methods. Since there is no need for a trumpet-shaped elastic piece made of a separate member, the structure can be simplified and manufacturing costs can be reduced.

Moreover, the bellows-shaped air pipe is fixed inside the instrument panel by a fastener, and the part that protrudes from the hole beyond that is free, and that part can be expanded and contracted in the axial direction. When the door is closed, the free end of the air pipe is pressed by the inner surface of the door, and the end face of the air pipe is elastically brought into close contact with the outer periphery of the entrance of the side defroster, and the air pipe itself becomes like a conventional elastic piece. Exactly the same effect can be performed, and the connecting portion of the side defroster with the artificial part can be effectively sealed.
